vegan nacatamal pie

A friend of ours recently left Colorado to travel the world and teach English. Her first destination will be Nicaragua. In the process of lightening her load, she left us with her crock pot. I thought it would be nice to expand my own horizons and make a Nicaraguan dish for our first crock pot meal. I honestly had no idea what Nicaraguan food was like until I looked it up. It's interesting how we seem to be satisfied with a certain number of ethnic foods (Chinese, Thai, Indian, Italian, Mexican) and ignore inspiration from other parts of the world.  Anyway, I made Nicaraguan nacatamal pie - a crock pot version of nacatamales which are fairly similar to Mexican tamales. Instead of using pork butt I made these vegetarian and added anasazi beans though small red beans would have been more authentic to Central American cuisine. Speaking of food diversity, wouldn't it be interesting to have more bean options on our grocery store shelves?

Filling Ingredients:
anasazi beans, cooked
rice, cooked
potatoes, sliced
bell peppers, sliced
tomatoes, sliced
onions, chopped
green olives, minced
achiote paste
mint
salt
black pepper

Topping Ingredients (adapted from The Cooking Bride):
2 c. instant Masa Harina
1 t. baking powder
¼ t. salt
2 c. veggie broth
½ c. olive oil

Mix the filling ingredients in a 6 qt. crock pot.  Mix the topping ingredients and glop it on top of the filling.  Cover and cook on low for 5 hours or until potatoes and masa dough are cooked.
